## Abstract A simple and versatile system is described for the onβline coupling of SFE to capillary GC. The interfacing consists of a programmed temperature vaporizer (PTV) injector. With this injector it is possible to combine solute trapping, elimination of a high flow of extraction fluid, and qu

A technique which allows the a priori determination of optimal density programs for supercriticalfluid chromatography (SFC) is proposed. This new approach is meant to supersede heuristic methods for optimizing molecular resolution in SFC. The analysis is based upon optimal control theory applied to
## Abstract When temperature programming is performed in supercritical fluid chromatography (SFC) under conditions where the soluteβmobile phase interactions are approximately fixed, that is, with the use of constant mobile phase density, then positive temperature programs can be used. The results
